SPI Operational Requirements
1. The data bits are transmitted with the LSB first.
2. The maximum clock rate is 10MHz for the CLK pin.
3. CLK must remain logic-high for at least 50ns (t
CH
) after
the rising edge of CLK, and CLK must remain logic-low for at
least 50ns (t
CL
) after the falling edge of CLK.
4. The serial data bits are sampled at the rising edge of CLK.
Any transition on DATA must occur at least 20ns (t
) before
the rising edge of CLK. Also, any transition on DATA must
occur at least 20ns (t
) after the rising edge of CLK and
stabilize before the next rising edge of CLK.
5. ENB should be logic-high only during serial data transmis-
sion.
6. ENB must be logic-high at least 20ns (t
) before the first
rising edge of CLK, and ENB has to remain logic-high at
least 20ns (t
EH
) after the eighth rising edge of CLK.
7. If ENB remains logic-low for more than 10ns before all 8
bits are transmitted then the data latch will be aborted.
8. If ENB is logic-high for more than 8 CLK pulses then only
the first 8 data bits will be latched and activated when ENB
transitions to logic-low.
9. ENB must remain logic-low for at least 30ns (t
EL
) to latch
in the data.
10. Coincidental rising or falling edges of CLK and ENB are
not allowed. If CLK is to be held logic-high after the data
transmission, the falling edge of CLK must occur at least
20ns (t
CS
) before ENB transitions to logic-high for the next
set of data.
